Layer breakdown
Polyfoam comfort layer
0.75″ thick · 1.8 lb/ft³ density
Measured at 1.8 lb/ft³ — solid polyfoam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 2.2 lb/ft³ here.
Polyfoam transition layer
1″ thick · 2.5 lb/ft³ density
Measured at 2.5 lb/ft³ — high-density foam like this resists softening and body impressions, one of the strongest longevity signals in a build.
Polyfoam transition layer
0.75″ thick · 1.8 lb/ft³ density
Measured at 1.8 lb/ft³ — solid polyfoam for average-weight sleepers, though heavier (200 lb+) sleepers would want closer to 2 lb/ft³ here.
Polyfoam transition layer
1″ thick · 1.5 lb/ft³ density
1.5 lb/ft³ foam runs light, but a 1″ slab like this is too thin to drag durability down.
Coil support core
8″ thick
An open coil core is the best airflow a mattress can have — body heat vents out instead of building up.
